SPECIFICATION forming part of Letters Patent No. 509,189, dated November 21, 1893.

Application filed July 11, 1893. Serial No. 480,158. (No model.)

T0 on whom it may concern.-

Be it known that I, ALLIE R. WELCH, a citizen of the United States, residing at Chelsea, in the county of Washtenaw and State of Michigan,have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful im provements in oil stoves, and the invention consists in the peculiar construction of the wick raising device.

The invention further consists in the peculiar construction, arrangement and combination of the various parts, all as more fully hereinafter described.

In the drawings, Figure 1 is avertical, central, longitudinal section through the oil tank of an oil stove and through the burner illustrating my wick raising device. Fig. 2 is an elevation of the wick tube and wick raising device, the tank not being shown. Fig. 3 is a detached perspective view of the actuating ring. Fig. 4. is a section on line 00a: of Fig. 2.

A is the oil tank.

B is the central tube extending vertically therethrough forming the inner wall of the wick tube.

B is a ring concentrically arranged outside the wick tube B at the top and forming the outer wall of said wick tube. This ring is preferably provided with an annular flange E the ring B and its flange being removable to permit the more ready application or removal of the wick. The top E of the oil tank is provided with an annular depression D around the wick tube B.

C is a ring or wall arranged around the wick on the wick tube and extending up from the top of the oil tank. .At its top it is provided with an outwardly extending flange D.

L is a movable ring sleeved about the wall or ring C beneath the flange D. This ring forms the actuating means for raising or lowering the wick.

G is the wick.

H are a series of arms each provided at its lower end with feet I, having spurs or pins I adapted to engage in the wick. These arms comprise the upper or straight portion a, the

intermediate inclined portion 1) and the foot portion. On the outer face of the foot portion is a lug cits upper face beveled as shown in Fig. 1. These arms pass through guide slots 6 in the top of the tank and at their upper ends they are provided with pins f which enter vertical slots h in the guide bar 2' and vertical slots h in the ring C and through spiral slots is in the ring L. The pin is preferably provided at its inner end with thehead Z as shown in Fig. 4 to prevent its accidental displacement. The sleeve or ringL is rotated by the hand wheel L on the shaft L which at its inner end is provided with the pinion M meshing with the rack M on the lower edge of the ring L, as plainly shown in Fig. 1.

U are a series of bars extending through the oil tank opposite the actuating arms H and near their upper ends provided with the inclined or beveled portion P.

The parts being thus constructed their oporation isas follows: Thewick being in position and the parts being substantially in the position shown in Fig. 1, theprongs I will engage into the wick and be held therein because of the'fact that the lugs c are arranged opposite and bear against the standards 0 preventing lateral movement of the feet I. To raise the wick the operator turns the hand wheel L which through the shaft L and pinion M will rotate the sleeve or ring L. This rotation will cause the pins f to be lifted up in the spiral slots in, the same being guided in vertical position by their engagement'with the vertical slots h in the ring C and the slots h in the guide bars 7). This motion will lift the arms H and with them will raise the wick. The reversemotion willlower the wick. When the wick approaches its uppermost position the inclined portion 1) of the arm H engaging through the guide apertures 6 will withdraw the feet I from the wick, allowing it to be withdrawn or adjusted. When properly adjusted the operator turns the ring L in the reverse direction causing the arms H to be lowered, the incline on the under face of the lug a will strike the inclined portion P of the standard and throw the spurs of the feet again into engagement with the wick. In order to prevent the accidental disengagement of the spurs from the wick I arrange a spring stop R in the path of a lug or stop R on thering L so as to stop the ring before the inclined portion b enters the guide slots 6 and when it is desired to withdraw the wick or adjust it by withdrawing the teeth on the feet I, the operator draws out the spring stop R allowing the lug to pass it, when further rotation of the ring will operate as described.

What I claim as my invention is 1. In an oil stove, the combination with-the oil tank, and the wick tube, of a wick raising device comprising a ring about the wick, having a series of spiral grooves therein, wick holding arms having pins engaging in said grooves, guide ways through which said arms work and an incline on said arms adapted to pass through said guide Ways to move them to and from the wick, substantially as described.

2. In an oil stove, the combination with the oil tank and the wick tube, of a wick raising device comprising a ring about the wick, a rack thereon, a pinion engaging the rack, an actuating shaft for the pinion, a series of arms having toothed feet engaging the wick, stationary guides beside the arms, lugs on the arms engaging said guides and also engaging spiral slots in the ring, guide ways for the arms, and an inclined portion on the arms ongaging the guide ways acting to move the toothed foot to and from the wick, substantially as described.

3. In an oil stove, the combination with the oil tank and wick tube, of a wick raising device comprisiug a ring sleeved about the wick, spiral slots in the ring, wick holding arm, having pins engaging the slots, means for releasing the wick holding arms from the wick at the top of their movement, and a lock to prevent the arms from reaching the disengaging point, substantially as described. a

4:. In an oil stove, the combination with the oil tank, the wick tube and the ring about the wick tube, having spiral slots, and actuating means for the'ring, of stationary guides beside the ring, arms I-I, having pins engaging in vertical slots in the stationary guides and in the spiral slots in the ring, guide ways in which the arms engage, the inclined portions having the inclined lower face, and the bars or posts beside the arms having vertical portions 0, and inclined portions P, the parts combined and operating, substantially as described.

5. In an oil stove, the wick raising device comprising the stationary sleeve 0 having vertical slots, the flange D at the top thereof, the ring L about the sleeve provided with spiral slots, wick raising arms, pins thereon, passing through the vertical and spiral slots, and actuating means for the ring L, substantially as described.

6. In an oil stove, the combination of the oil tank and the wick tube, of a wick raising device comprising a ring surrounding the wick having a series of inclined slots therein, wick holding arms adapted to engage the wick and having pins engaging said slots, stationary bearings through which said arms are guided vertically, a rack on the ring, and a pinion and shaft for turning the ring, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
